Clean Python files.
Zero logic changes.
A lightweight command-line tool that automatically cleans whitespace and formatting issues in Python files — without touching your code's logic.
Why Python File Cleaner?
Whitespace problems are one of the most frustrating issues in Python projects. We solved them so you don't have to.
Prevents Syntax Errors
Automatically fixes the most common whitespace-related syntax errors that plague Python projects.
- Converts tabs to spaces automatically
- Cleans line continuations after backslashes
- Normalises line endings (CRLF/LF)
Keeps Git Diffs Clean
Stop committing whitespace changes. Keep your version control history focused on actual code changes.
- Removes trailing spaces instantly
- Reduces whitespace-only commits
- Prevents unnecessary merge conflicts
Safe File Handling
Your code is precious. We treat it that way by never overwriting files without a backup.
- Never overwrites original files directly
- Automatically creates cleaned copies
- Customizable output filenames
Simple Interactive Interface
You're in control. Choose exactly what you want to clean with clear prompts.
- Clean syntax issues only
- Optimize for file size
- One-click 'Clean Everything' mode.
Safe by Design
Python File Cleaner never changes your program's behavior. It strictly handles formatting and whitespace, ensuring your logic remains 100% intact.
Guaranteed Safe Operations
-
Never modifies logic or algorithms
-
Never renames variables or functions
-
Never reorders imports
What It Is Not
To stay safe and predictable, Python File Cleaner intentionally avoids advanced code manipulation.
Not a Linter
Unlike flake8, it doesn't complain about your style—it just fixes whitespace.
Not a Formatter
Unlike black, it doesn't enforce opinionated line lengths or wrapping.
Not a Refactorer
It won't extract methods or change your variable names.
